As I mentioned I am very new at linux and fedora 23 is my first distro ever. Put "how to install headers in fedora 23" in your favorite search engine and follow the instructions.I don't know if I have installed Kernel headers, neither I know how to do or check. echo Your kernel headers for kernel 4.4.7-300.fc23.i686 PAE cannot be found at/lib/modules/4.4.7-300.fc23.i686 PAE/build or /lib/modules/4.4.7-300.fc23.i686 PAE/source.

Note on a VPS (for instance a Linode VPS), a kernel may have a customized version name, in such scenario, you have to identify the kernel version manually and check the installed kernel header files using following commands.
